NASA Crashes the Moon Tomorrow Morning

One of the coolest-sounding missions launched by NASA comes to an explosive end tomorrow morning. The Lunar CRater Observation and Sensing Satellite (or LCROSS) will smash into the moon at about 4:30 a.m. PST (7:30 a.m. EST), followed by another impact four minutes later.

The first stage of the LCROSS is designed to kick up a huge plume of dust in the permanently dark Cabeus crater at the south pole of the moon. The second stage contains scientific equipment to collect the dust and determine if it contains water ice, before crashing into the moon itself and causing a purely gratuitous explosion.

According to the mission’s NASA page, amateur astronomers with a 10 to 12-inch telescope should be able to see the dust plumes created by the impacts.

If water ice is found in the dust, it would confirm findings of water and hydroxyl molecules by NASA instruments aboard the Indian Space Research Organization’s Chandrayaan-1 spacecraft launched about a year ago.
